NEW YORK -- Dennis Seidenberg played only one shift in Tuesday night’s 2-1 win over the Rangers before leaving with a lower-body injury. Seidenberg was injured during a net-front tangle with Derek Dorsett. Seidenberg stayed on the ice but left after his shift, favoring his left leg.

Seidenberg was on the ice for 61 seconds. It is unknown whether Seidenberg will be available for Thursday’s home game against St. Louis.

Seidenberg has played in all 21 games. He has no goals and six assists. Seidenberg has been the left-side defenseman on the No. 2 pairing with Torey Krug.

It was the third time this season the Bruins lost a defenseman mid-game. Johnny Boychuk hurt his back in the second period of the 3-2 shootout win over Anaheim Oct. 31. Adam McQuaid was hurt in the first period of the 3-1 win over Toronto Nov. 9 when turning and pursuing a puck.

Because of Seidenberg’s injury, Zdeno Chara played a season-high 31:27. The Bruins matched Chara against the Rangers’ top line of Rick Nash, Brad Richards, and Ryan Callahan. Chara was credited with five hits and three blocked shots.

“It says a lot,” coach Claude Julien said of his five healthy defensemen assuming more shifts. “This is not just a game. This is a back-to-back game with travel. I thought they did a good job. I look at Zdeno at the end and how he was strong, poised, and getting pucks out of our own end. There wasn’t much panic.”

Matt Bartkowski hurt his left knee in the second period. Callahan belted Bartkowski, sending him into the boards. Bartkowski limped off the ice. He recovered on the bench and finished the game (21:13 of ice time, two shots, one hit).
